METAL POLE.

My invention relates to a metal pole or post for supporting telephoneand telegraph lines or the like, but adapted to be used for any otherpurpose for which the pole may be found appropriate. It is an object ofthe in vention to provide a simple and inexpensive pole or post ofminimum weight and n1aximum carrying strength, as well as one that willbe durable and substantially permanent in use, and by the employment ofwhich numerous disadvantages encountered in the use of poles or posts ofwood or other mate rial of like nature will be obviated, all as will behereinafter more particularly described and claimed.

Referring to the drawings, which are made a part hereof and in whichsimilar reference characters indicate similar parts,

Figure 1 is an elevation of a pole constructed in accordance with myinvention, set in the ground, I

Figure 2, a detail perspective of the lower portion of the pole,

Figure 3, a diagrammatic plan view of the top of the the pole, and

Figures 4, 5, and 6, detail views of other forms of members which may beused.

In the drawings a pole or post is shown constructed of a series ofmembers or strands of inverted V-shaped cross-section, a portion ofwhich extend in a spiral direction lengthwise of the pole and anotherportion extend lengthwise of the pole in a spiral direction reverse tothat of the first portion.

In the drawings a group of inside inembers 10 are formed in a spiralwhich extends from one end of the pole to the opposite end, and a groupof outside members 11. which also extend from one end of the pole to theother end, and in a direction opposite the first group. The members ofeach group cross the members of the opposite group at regular intervalsthroughout the length of the pole and the edges of the members of onegroup contact with the edges of the members of the opposite group atsuch crossing points, as shown in Fig. 3, and form a cross section ofsubstantially diamond shape. The contacting edges are preferably securedtogether by electric butt-welding at 12, or by any other convenientmethod. Electrically butt-welding the contiguous edges is much moreeffective than spot-welding and also much less expensive.

Wide metal bands 13 are provided at the 1927. Serial N0. 196,111.

extremities of the pole between the spiral members 10 and 11 and suchbands are pref erably secured in the same manner in which the contiguousedges of the bars are secured. It is also desirable to place a similarwide band 14 at the ground line where the greatest strain is placed uponthe pole when in use, since such band reinforces the pole. Also, if

desired, bandsmay be placed at different points along the length of thepole,

lVhile I have illustrated a pole which (on sists of fourteen spirallywound members of particular shape in cross section, a greater or lessnumber or members may be employed and, as illustrated in Figs. 4 to 6,members of different shape may be substituted and. the size may bevaried according to the strength and rigidity of pole desired. reason ofthe special construction of my pole, the particular type of membersused, and the manner in which they are secured together inthe spiralform shown, a pole of comparatively small amount of material is providedwhich is capable of withstanding comparatively great strain, the partsbeing so positioned that each member sup plemcnts the other in resistingstress and lending strength and stability to the structure.

It will be obvious to those skilled in the art that poles or postsforming the subjectmatter of this invention may be made of any lengthand size desired and that the members need not necessarily be woundspirally but, on the other hand, a pole of polygonal cross section maybe formed to adapt the same for any particular use or purpose and I,therefore, no not limit myself to what is shown in the drawings anddescribed in the specification, but only as set forth in the appendedclaims.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is:

1. A post formed of two groups of spirally disposed members, one groupwound right hand and the other group wound left hand, each member havinglegs whose edges are connected with the edges of the corresponding legsof the other members at crossing points, substantially as set forth.

2. A pole or post comprising two groups of spirally arranged members,the members of one group extending spirally in one direction and havinglegs presented to legs of the group which extends in an opposite spiraldirection at crossing points substantially as set forth.

3. A pole or post comprising two groups .of spirally arranged members,the members of one group extendingspirally in one direction and havinglegs presented to legs of the group which extends in an opposite" spiraldirection at crossing points, said members being connected at crossingpoints, substantially as set forth.

4. A pole or post comprising a group of members extending from one endof the pole about the same to the opposite end, a second group ofmembers ext-endingfrom one end of the pole about thesamein a directionopposite the first group to the opposite end of the pole, the members ofeach group presenting. thin leg portions tothe members of the othergroup, and the thin leg portions of said groups being connected atcrossing points, substantially as set forth.

5. A pole or post comprising a group of angle memberswxtcntling Tour oneen t of the pole to theoppositend; a second group of anglemembersextendiiigfronr one end of the pole in a direction opposite thelust group to the opposite end of the pole, the

members of each group having their angles
